(3.0 cr; Prereq-3235; A-F or Aud)
Power semiconductor devices; traditional power converters; ac-dc converters: halfwave and full-wave rectifiers; dc-dc converters: traditional and transformer derived choppers; dc-ac converters: single-phase and three-phase inverters; ac-ac converters; pulse-width modulation; applications.
Educational Goals:
This course provides a broad overview of the engineering concepts associated with design, analysis and control of solid-state power converters. In-depth emphasis is placed on
Course Outcomes (indexed to ABET ):

Apply differential calculus to transient RLC circuits (a)

Linearize inherently non-linear circuit operation into piecewise linear operating states (a)

Design, build and test simple DC-DC converters(e)

Simulate DC-DC converter operation using
PSPICE or PowerSim (c)

Design and simulate fly-back converters (c,e)

Design and simulate DC-AC converters (c,e)

Explore design trade-offs related to efficiency, capacity and low-pass filtering requirements (e)

Recognize current and future applications in consumer electronics and electric utilities. (k) selected topics including semiconductor power switches, DC-DC converters, DC-AC
Converters, Fly-back Topologies, High
Frequency Magnetics, Voltage Control,
Current Control, Variable Frequency Control and Utility Applications
The student gains skills and understanding in the areas of modeling and analysis of switchmode operation, linearization of non-linear behavior, design constraints on operation and efficiency and filter design.
PSPICE or PowerSIM is used to reinforce concepts in the analysis of switch-mode operation, non-linear behavior and design trade-offs related to efficiency.
